Energy holds supercomputing high ground

Energy holds supercomputing high ground

The government has the four fastest computers in with world, and 75 of the 500 fastest, as ranked on a semiannual list updated last week on the Web at www.top500.org.

Federally funded supercomputers captured seven of the top 10 spots on the latest list. Three Energy Department computers and a brand-new Navy machine hold the top four positions.

Another 13 federally funded systems appear on the list. Twenty-two of the 75 federal computers are listed as classified, without specifying a funding agency.

As in past years, Energy's Accelerated Strategic Computing Initiative, a program for simulating on massively parallel computers the aging of nuclear weapons, tops the list.

The Intel ASCI Red supercomputer at Sandia National Laboratories in Albuquerque, N.M., remains No. 1 with a Linpack performance of 2.38 trillion floating-point operations per second.

Two other ASCI machines, Blue Pacific at Lawrence Livermore National Laboratory in Livermore, Calif., and Blue Mountain at Los Alamos National Laboratory in Los Alamos, N.M., remained second and third.
